Abstract
A printing cylinder/roller cleaning apparatus for a printing press includes a cleaning cloth (6), a take-up roll (14), a supply roll (8), a ratchet wheel (10), a lock lever (30), a swing lever (18), a one-way clutch (15), and an air cylinder (25). The cleaning cloth is pressed against a circumferential surface of a rotating printing cylinder/roller (2). The take-up shaft takes up the cleaning cloth. The supply roll supplies the cleaning cloth. The ratchet wheel is coaxially mounted on the supply roll. The lock lever engages with the ratchet wheel when the cleaning cloth is not taken up. The swing lever is coaxially mounted on the take-up roll and rotated to actuate the lock lever, thereby releasing engagement between the ratchet wheel and the lock lever. The one-way clutch connects the take-up roll with the swing lever only in a direction to take up the cleaning cloth. The air cylinder pivots the swing lever in response to the cleaning operation of the printing cylinder/roller.
Description
- The present invention relates to a printing cylinder/roller cleaning apparatus for a printing press, which cleans the circumferential surface of a printing cylinder, e.g., a blanket cylinder, an impression cylinder, or a transfer cylinder, and the circumferential surface of a roller, e.g., a form roller or a vibrating roller.
- Generally, a printing cylinder/roller cleaning apparatus of this type has a cleaning cloth take-up mechanism comprising a pair of rotatably supported roller-shaped cloth guides pressed against the circumferential surface of a printing cylinder/roller through a cleaning cloth, a supply shaft for supplying the cleaning cloth to the cloth guides, and a take-up shaft for taking up the cleaning cloth supplied from the supply shaft. The cleaning cloth is pressed against the circumferential surface of the printing cylinder/roller by intermittently taking up the cleaning cloth on the take-up shaft from the supply shaft, and the residue, e.g., ink dust or paper dust on the circumferential surface of the printing cylinder/roller is wiped with the cleaning cloth, thereby cleaning the circumferential surface of the printing cylinder/roller. In this case, when the cleaning cloth is taken up in the downstream side of the printing cylinder/roller, the cleaning cloth can be undesirably caught in the printing cylinder/roller. Thence, a countermeasure must be provided with regard to the supply shaft such that the cleaning cloth will not be pulled unless the cleaning cloth is taken up.
- An example of an apparatus provided with such a countermeasure is a cylinder cleaning apparatus disclosed in Japanese Patent Laid-Open No. 2-20349. In the cylinder cleaning apparatus disclosed in this document, a rotation stop mechanism comprising a ratchet wheel mounted on the shaft end of a supply shaft, a ratchet to be engaged with this ratchet wheel, an air cylinder for engaging and disengaging the ratchet with and from the ratchet wheel, and a spring for biasing the ratchet away from the ratchet wheel are provided to the supply shaft. When the cleaning cloth is to be taken up on the take-up shaft, while the ratchet is separated from the ratchet wheel by the biasing force of the spring, the take-up shaft is driven by a take-up driving unit to take up the cleaning cloth. Unless the cleaning cloth is to be taken up, the ratchet is engaged with the ratchet wheel against the biasing force of the spring by the operation of the air cylinder as the driving unit of the rotation stop mechanism, so that rotation of the supply shaft in the supply direction is prohibited, thereby preventing the cleaning cloth to be pulled out.
- However, in the conventional cylinder cleaning apparatus described above, the driving unit for driving the rotation stop mechanism comprising the air cylinder is required in addition to the take-up driving unit for the take-up shaft. In addition, since take-up driving of the take-up shaft and rotation regulation release of the supply shaft must be performed almost simultaneously, when the take-up driving mechanism and the rotation stop mechanism respectively having a separate driving means are to be interlocked, the entire apparatus is increased in size, and the operation becomes complicated, so that a smooth operation cannot be obtained.
- It is an object of the present invention to provide a printing cylinder/roller cleaning apparatus for a printing press, whose size can be decreased as a whole.
- It is another object of the present invention to provide a printing cylinder/roller cleaning apparatus for a printing press, in which take-up operation and pull-out prevention of the cleaning cloth are smoothly associated with each other.
- In order to achieve the above objects, according to the present invention, there is provided a printing cylinder/roller cleaning apparatus for a printing press, comprising a cleaning cloth pressed against a circumferential surface of a rotating printing cylinder/roller, a take-up shaft for taking up the cleaning cloth, a supply shaft for supplying the cleaning cloth, a ratchet wheel coaxially mounted on the supply shaft, a lock member engaged with the ratchet wheel when the cleaning cloth is not taken up, an actuating member, coaxially mounted on the take-up shaft and rotated, for actuating the lock member, thereby releasing engagement between the ratchet wheel and the lock member, a first one-way clutch for connecting the take-up shaft with the actuating member only in a direction to take up the cleaning cloth, and driving means for pivoting the actuating member in response to the cleaning operation of the printing cylinder/roller.

- Fig. 1B is a view showing a state wherein a cleaning cloth is being taken up;
- Fig. 2A is a view showing a state wherein the apparatus shown in Fig. 1A starts operation of taking up the cleaning cloth; and
- Fig. 2B is a view showing a state wherein the operation of taking up the cleaning cloth is completed.
- A preferred embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1A shows a printing cylinder/roller cleaning apparatus for a printing press according to an embodiment of the present invention, Fig. 1B shows a state wherein a cleaning cloth is being taken up, Fig. 2A shows a state wherein an operation of taking up the cleaning cloth is started, and Fig. 2B shows a state wherein the operation of taking up the cleaning cloth is completed. Referring to Figs. 1A to 2B,
reference numeral 2 denotes a blanket cylinder pressed against an impression cylinder (not shown). Roller-shaped cloth guides blanket cylinder 2. A belt-like cleaning cloth 6 extends between thecloth guides blanket cylinder 2. Thecleaning cloth 6 is supplied from acloth supply shaft 8 and taken up by a take-up shaft 14 driven by a take-up mechanism (not shown). -
Reference numeral 10 denotes a ratchet wheel having a circumferential surface formed withteeth 10a and coaxially mounted on ashaft 8a of thesupply shaft 8. Theratchet wheel 10 is connected to thesupply shaft 8 through a one-way clutch 11 so that when theratchet wheel 10 is fixed, rotation of thesupply shaft 8 in a direction to supply thecleaning cloth 6 is prohibited. An L-shaped swing lever 18 is swingably supported by ashaft 14a of the take-up shaft 14 as the swing shaft. The take-up shaft 14 is connected to theswing lever 18 through a one-way clutch 15 so that the take-up shaft 14 is rotatable only in a direction to take up thecleaning cloth 6. - An
abutting block 19 is mounted on one end of theswing lever 18, and aroller 20 is provided on a rear surface of the other end of theswing lever 18. Theabutting block 19 is coupled to the distal end of arod 26 of anair cylinder 25 serving as an actuator. Theswing lever 18 is swung about theshaft 14a by therod 26 moving forward/backward from/into theair cylinder 25. -
Reference numeral 30 denotes a substantially T-shaped lock lever supported to be swingable about ashaft 31. Thelock lever 30 has one end provided with aratchet 30a. Theratchet 30a is engaged with theteeth 10a of theratchet wheel 10 to prohibit rotation of theratchet wheel 10 in a direction to supply thecleaning cloth 6, i.e., counterclockwise in Fig. 1A. Acam surface 30b on which theroller 20 of theswing lever 18 slides is formed on the upper end face of thelock lever 30. Thelock lever 30 is imparted with a swing habit by acompression spring 33 clockwise in Fig. 1A, i.e., in a direction such that itsratchet 30a engages with one of theteeth 10a of theratchet wheel 10. -
Reference numeral 34 denotes a V-shaped swing lever 34 swingable about itsshaft 34a. Astopper pin 35 and aroller 36 for regulating the swing amount of theswing lever 18 are axially mounted on the swing end of theswing lever 34. Theswing lever 34 is always imparted with a swing habit counterclockwise so that theroller 36 abuts against the circumferential surface of the take-up shaft 14. When the take-up diameter of the take-up shaft 14 increases, theswing lever 34 is gradually moved against the swing habit, and accordingly thestopper pin 35 is also moved clockwise. Then, the counterclockwise swing amount of theswing lever 18 abutting against thestopper pin 35 is regulated to be small, so that the take-up amount of thecleaning cloth 6 defined by the swing amount is adjusted almost at a constant value. That is, a predetermined length of the cleaningcloth 6 can be constantly taken up by one take-up operation regardless of the take-up diameter of the take-up shaft 14. - The operation of this printing cylinder/roller will be described. During cleaning of the
blanket cylinder 2, theair cylinder 25 is actuated to move therod 26 forward, so that a soiled portion of thecleaning cloth 6 is taken up and a clean portion of thecleaning cloth 6 is supplied through thecloth guides rod 26 is moved forward, the swing lever 18 swings counterclockwise about theshaft 14a. At this time, since theswing lever 18 is coupled to the take-up shaft 14 through the one-way clutch 15 so that the take-up shaft 14 is rotatable only counterclockwise, the cleaningcloth 6 will not adhesively attach to an ink tack or the like and be pulled out from the take-up shaft 14 to theblanket cylinder 2. - When the swing lever 18 swings counterclockwise, the
roller 20 slides on thecam surface 30b of thelock lever 30 from the state shown in Fig. 1A, and swings thelock lever 30 counterclockwise against the biasing force of thecompression spring 33. Hence, as shown in Fig. 2A, theratchet 30a is separated from the corresponding one of theteeth 10a of theratchet wheel 10 to release engagement between theratchet 30a and the corresponding one of theteeth 10a, and theratchet wheel 10 is released and may rotate . - The
supply shaft 8 is connected to theratchet wheel 10 through the one-way clutch 11 so that thesupply shaft 8 will not rotate counterclockwise. When theratchet 30a and the corresponding one of theteeth 10a are engaged with each other, the cleaningcloth 6 will not be pulled out. As described above, when engagement between theratchet 30a and the corresponding one of theteeth 10a is released, thesupply shaft 8 is rotated counterclockwise, together with theratchet wheel 10, about theshaft 8a. Thus, a clean portion of the cleaningcloth 6 is pulled out, supplied, and taken up by the take-upshaft 14. - As the
rod 26 is moved forward, when theswing lever 18 abuts against thestopper pin 35, as shown in Fig. 2B, rotation of thesupply shaft 8 connected to theswing lever 18 is stopped, and the take-up operation of the cleaningcloth 6 is completed. Thereafter, when therod 26 starts to be moved backward, theswing lever 18 swings clockwise, and accordingly thelock lever 30 is also caused to start swinging clockwise by the restoring force of thecompression spring 33. When theroller 20 is disengaged from thecam surface 30b, theratchet 30a of thelock lever 30 engages with the corresponding one of theteeth 10a of theratchet wheel 10, and thesupply shaft 8 is also locked by the one-way clutch 11 which is connected to theratchet wheel 10 such that its counterclockwise rotation is disabled. Hence, the cleaningcloth 6 will not be pulled out from thesupply shaft 8 unless it is taken up. This operation is repeated by intermittently moving therod 26 forward/backward, so that the cleaningcloth 6 is intermittently taken up. - In this embodiment, the printing cylinder/roller to be cleaned with the cleaning
cloth 6 is theblanket cylinder 2. However, the present invention is not limited to this, and can naturally be applied to any other printing cylinder or a rotating roller. The cleaningcloth 6 is pressed against the circumferential surface of theblanket cylinder 2 by the pair of roll-shaped cloth guides 3 and 4. However, the present invention is not limited to this, and various design modifications can be made. Theswing lever 18 and thelock lever 30 are interlocked with each other through theroller 20 and thecam surface 30b. However, the present invention is not limited to this, and theswing lever 18 and thelock lever 30 may be coupled through a link mechanism. Alternatively, in place of theswing lever 18, for example, a pinion may be axially mounted on the take-upshaft 14, therod 26 may be provided with a rack to be meshed with the pinion, and thelock lever 30 may be directly coupled to therod 26. In this case, the pinion and thelock lever 30 need not be swingable, and thecompression spring 33 for biasing thelock lever 30 can be eliminated. In place of theair cylinder 25, an actuator may be adopted as the actuator, as a matter of course. Theratchet wheel 10 is coupled to thesupply shaft 8 through the one-way clutch 11. However, it is apparent that a similar effect to this can be obtained even by integrally coupling theratchet wheel 10 with thesupply shaft 8. - As has been described above, according to the present invention, since the air cylinder serving as the driving means of the take-up shaft is used also as the driving means for releasing rotation regulation of the supply shaft, thus eliminating an exclusive driving means, the apparatus can be reduced in size. Furthermore, since the supply and take-up operations of the cleaning cloth can be performed in an interlocked manner by the operation of a single driving means, a smooth take-up operation and pull-out prevention of the cleaning cloth can be obtained.
